Matching LCDs to cell phones
« on: March 21, 2014, 09:32:30 am »
I would like to find a 2 inch LCD from a cell phone for my project. Adafruit has a really nice one here: http://www.adafruit.com/products/1480

Where I live it is a lot easier to find LCDs locally than to have them shipped but I would have to know the phone model it came out of. Is there any way to find this out? Googling the chipset (ILI9340) and the LCD model (TM022HDH26) didn't turn anything up.

Any other LCD with at least a 2 inch color screen, a solderable ribbon, and working code will work if you know the phone it came from. Any suggestions?

Where I live
Where's that?
I didn't take it apart.
I turned it on.

The only stupid question is, well, most of them...

Most of the use one of a few standard controllers, so it shouldn't be too hard to get them working.

@Rasz, those are really neat but none of those are solderable. They all use little board connectors. (Don't mean to be picky but I don't think I could solder wires to one of those.)

@amyl, that's true but figuring out the pin outs and voltages with no datasheet is pretty difficult. You won't even know if it is I2C or SPI. I have a quite a few LCDs that I know absolutely nothing about.

If you don't manage to or can't revers engineer the interface of a random LCD then the solution is rather simple:

  • The seller has to tell you where it comes from.
  • You then cross-check if there is sufficient information on the Internet how to use that LCD.
  • You further check if you can solder it or can get a solderable connector/cable for it.

If the seller can't tell you, or you can't find information about it on the Internet don't buy the particular LCD.

If you can't solder it and if you can't obtain a suitable, solderable connector/cable then again don't buy that LCD.


So what exactly is your problem? The remaining potential candidates available in your country (wherever that is, you refused to tell), being zero? Bad luck.

@Bored@Work, I'm in Kyrgyzstan. Like I said, I can find LCDs if I know the phone name. You should reread the thread. You don't seem to understand what we are talking about. Obviously you should not buy an LCD you don't know anything about. That is the whole point of my question. I'm looking for one that I know will work AND what phone it came from so I can go and buy it.
